V4L/DVB (11945): uvcvideo: Don't accept to change the format when buffers are allocated.

Setting a new frame format or size will likely change the buffer size required
to store a complete video frame. To avoid a buffer overflow, don't allow
VIDIOC_S_FMT calls when video buffers are already allocated.
